Abstract

Automatic lighting control systems, devices, and methods that automatically control a light source in response to detected computer usage by a user are disclosed. The automatic lighting control method comprises monitoring usage of a computer and controlling an output of a light based on the usage. The system comprises a computer configured to detect usage of the computer by a user, a central server, a lighting controller unit, and a light source that is controlled based on the usage of the computer. The usage is selected from the group consisting of a key stroke, a mouse movement, a use of a peripheral device operatively coupled to the host computer, and any combination thereof.

Claims

1. A method of automatically controlling a load circuit comprising:

a) monitoring usage of a host computer by a user present at a location corresponding to the host computer to generate usage data from the host computer;

b) transmitting the usage data to a controller unit; and

c) controlling an output of the load circuit corresponding to the location of the host computer with the controller unit based on the usage data generated from the host computer.

2. The method of claim 1, wherein the load circuit controls a light corresponding to the location of the host computer.

3. The method of claim 1, wherein the usage data is generated by an activity performed on the host computer, the activity selected from the group consisting of a key stroke, a mouse movement, a use of a peripheral device operatively coupled to the host computer, and any combination thereof.

4. The method of claim 2, wherein the step of controlling causes one or more of flashing the light on and off, turning the light off, turning the light on and dimming the light.

5. A method of automatic lighting control comprising:

a) communicating activity data generated from user activity on a host computer at a location of the host computer and transmitted to a central server at a location of the central server; and

b) operating a controller unit from the central server to control lights at or near the location of the host computer based on the activity data generated on the host computer.

6. The method of claim 5, wherein the activity data is generated by one or more activity is performed on the host computer, the one or more activities being selected from the group consisting of a key stroke, a mouse movement and a use of a peripheral device operatively coupled to the host computer.

7. The method of claim 5, wherein the step of operating a controller unit from the central server to control lights causes the lights to turn on, turn off or dim.

8. A method of automatic lighting control comprising:

a) monitoring a level of usage of a host computer by a user from the host computer to generate activity data;

b) transmitting the activity data to a controller unit coupled to a load circuit that controls light output corresponding to a location of the host computer; and

c) controlling the light output from the controller unit based on the activity data generated from the host computer.

9. The method of claim 8, wherein monitoring a level of usage of a host computer comprises monitoring one or more of key strokes from the host computer, mouse movements from the host computer and usage of a peripheral device operatively coupled to the host computer.

10. The method of claim 9, wherein the peripheral device is selected from the group consisting of a keyboard, a monitor, a mouse, a printer, a modem, a CD-rom drive, a hard-drive, a USB device, a joystick, a touch screen, and any combination thereof.

11. The method of claim 8, wherein controlling the light output form the controller unit based on the activity data comprises reducing the light output when the a level of usage is below a threshold level and increasing the light output when the a level of usage is above the threshold level.

12. A system for automatic lighting control, the system comprising:

a) a host computer configured to detect a user'"'"'s usage of the host computer while the users is present at the host computer;

b) a controller in communication with the host computer; and

c) software loaded on host computer and configured to compile and transmit activity data to the controller based on the user'"'"'s usage of the host computer, wherein the controller is configured to control a light source at the host computer based on the transmitted activity data.

13. The system of claim 12, wherein the data is transmitted to the controller at intervals pre-selected by the user.

14. The system of claim 12, wherein the user'"'"'s usage of the host computer is selected from the group consisting of a key stroke, a mouse movement, a use of a peripheral device operatively coupled to the host computer, and any combination thereof.

15. The system of claim 12, wherein the activity data is transmitted to the controller by one or more of an Internet Protocol means, a wireless means, an infrared means, a radio means, an Ethernet network connection means and a hard wire connection means.

16. The system of claim 12, wherein the activity data comprises a user identifier and a location of the host computer.

17. The system of claim 12, wherein the activity data comprises a user override instruction configured to instruct the central server to maintain the light source on for a set period of time, regardless of the user'"'"'s usage of the host computer.

18. The system of claim 12, wherein the host computer comprises a Windows®

interface.

19. The system of claim 12, wherein the host computer comprises a Windows®

based computer icon software.

20. The system of claim 12, wherein the host computer comprises a UNIX interface.

21. The system of claim 12, wherein the host computer comprises a graphical user interface.

22. The system of claim 12, wherein the system further comprises a central server and wherein the activity data is transmitted to the controller through the central server.

23. The system of claim 22, wherein the central server is further configured to compile a historical activity log of the activity data.

24. A system for automatic lighting control comprising:

a) a plurality of light sources at a plurality of locations;

b) a controller unit configured to communicate with and to control light outputs from the plurality of light sources; and

c) a plurality of host computers at the plurality of locations each configured to send signals to the controller unit, wherein the signals instruct the controller unit to control the light outputs from the plurality of light sources at each of the plurality of locations based on a level of usage from each of the plurality of host computers at each of the locations.

25. The system of claim 24, wherein the system further comprises a plurality of receiver modules operatively coupled to the plurality of light sources, wherein the plurality of receiver modules are configured to receive control commands from the controller unit and to thereby control the light outputs from the plurality of light sources.

26. The system of claim 25, wherein each of the plurality of host computers include a signaling device to send the signals to the controller unit.

27. The system of claim 24, wherein each of the plurality of light sources is powered by a load and wherein the controller unit is configured to directly control the load.

28. The system of claim 24, wherein each of the plurality of light sources comprises a lamp, a ballast, and a lighting fixture.
